COMBINATION TOOL.

Application filed August 18, 1921. Serial NO. 493,389.

T 0 all whom it may concern:

Be it known that I, THOMAS H. BARTLETT, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented a new and useful Combination Tool, of which the following is a specification.

The device forming the subject matter of this application is a tool, adapted to be used by carpenters, and the invention aims to provide a structure of the sort above mentioned which will embody the functions of a number of dillerent instruments, thereby rendering it unnecessary for acarpenter to carry several tools in his kit.

The invention aims to provide a compound tool including a trysquare, a miter square, a plumb, a level and the like.

The invention aims, further, to provide novel means whereby the blade may be shifted, adjusted and held.

In the accompanying drawings:-

Figure 1 shows in side elevation, a device constructed in accordance with the invention; Figure 2 is a section on the line 2-2 of Figure 1; Figure 3 is a section on the line 3-3 of Figure 1; Figure 4 is a section on the line 44 of Figure 3, parts being broken away; Figure 5 is a detail sectional view; Figure 6 is a perspective view showing one of the disks; Figure 7 is a perspective view showing the arm.

The tool forming the subject matter of this application includes an approximately triangular body 1 provided-with a slot 2 in one of its angles 3 Figures 3 and 4. The edges of the body 1 are denoted by the numerals 4, 5 and 6. A vial 7 is disposed parallel to the edge 5 and is located between transparent plates 8 held in place by any securing means 9. A vial 10 is disposed parallel to the edge 6, a vial 11 being disposed parallel to the edge 4, the vials 10 and 11 being located behind plates 8 of the sort hereinbefore described, the plates being retained as hereinbefore explained. About its edge, the body 1 is supplied with a transverse fiange 12, which enables the body to be fitted the more readily to the work. The body 1 has an approximately central opening 14 and is provided with annular seats 15, Figure 3, there being a slot 20 between the inner portions of the seats 15.

In one of the seats 15, a disk 16 is rotatably mounted, a disk 17 being located rotatably in the other seat 15. The disk 16 is cut away transversely to form a shoulder 18, as shown in Figure 6, and is provided with a transverse slot or guide way 19, locatedat an angle to the shoulder. The disks 16 and 17 may be held together for simultancous rotation, through the instrumentality of dowel pins 21 or the like. The disks 16 and 1.7 are connected by a securing element 31', such as a bolt, the head of which engages a washer 33 cooperating with the disk 16, the securing element carrying a nut 34 bearing against the disk or plate 17. The disk 17 is provided with an index 35, Figure 1 adapted to cooperate with graduations 36 formed on one of the members 15, as shown in Figure 1.

An arm 22 is mounted for endwise sliding movement in the slot 19 of the disk 16. At its outer end, the arm 22 is cut away to form a thinned portion 24 and to form a transverse shoulder 23. The thinned portion 24 of the arm has a transverse rib 25. The arm 22 has an elongated slot 26. The securing element 31 passes through the slot 26. The arm 22 embodies a reduced threaded stem 27 mounted to move in a slot 20 of the body 1, a nut 28 being threaded on the stem and being adapted to cooperate with the inner portions of the annular seats 15, as shown in Figures 1 and 3. A blade 29 is located in the slot 2 of the body 1 and rests against the shoulder 18 of the rotatable disk 16, the thinned end 24 of the arm 22 extending behind the blade 29, as shown in Figure 3. The blade 29 is provided with an elongated groove 30 extended from one end of the blade to the other, and adapted to receive the rib 25, the rib and the groove 30 constituting interengaging elements.

In practical operation, the edge 5 of the body 1, in connection with the vial 7 forms a level, the edges 4 and 6 together with their respective vials 11 and 10 being adapted to be used as levels or plumbs. Angles may be marked on the work along the edges 5 and 6 or along the edges 5 and 4. The blade 29 may be set at any desired angle with respect to the edge 4, the index 35 cooperating with the graduations 36 to indicate the angle. In Figure 1, the blade 29 is set at such an angle with respect to the edge 4 as to enable the tool to be used as a square. The blade 29 may be shifted endwise along the shoulder 18, so that more or less of the blade will project to the right or to the left of the body 1, reference being Then, the blade 29. is connected to the disks 16 and 17, for swinging movement, when the disks are rotated. When the nut 28 is tightened up against the inner edges of the seats 15, the disks 16 and 17 will be held against rotation.

It will be seen that the instrument form ing the subject matter ofthis application is capable of a wide variety of uses, and will serve to replace many separate tools commonly found in a carpentefls kit.

A screw or like stop member, denoted by the numeral 50, Figures 1 and 5', may be threaded into the body 1 and be located in the path 01 the blade 29, to hold the blade in the position shown in Figure 1 of the drawings.

I claim r r In a device of the class described a body, disks rotatable on the body, one disk having 'a transverse shoulder and being provided with a guide-way disposed at an angle there to, a blade slidable for adjustment on the shoulder, a securing, element connecting the disks, an arm slid-ablein the guide-way and having an elongated slot receiving the securing element, the arm having a thinned end extended between the blade and said disk, the thinned end of the arm and the blade having interengaging elements which coact to hold the blade on the shoulder for sliding movement longitudinally of the lade, and a tightening element on the arm and coacting with the body tomove the arm endwise, thereby to clamp the blade on the shoulder and to hold the disks against rotation on the body. 1

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

THOMAS HERBERT BARTLETT.
